Polycarbonate Track Etch Membrane Disc Filters, 1.0um, 25mm, Hydrophilic, Nonsterile, 100/Pk
GVS SKU: 1215627

Featuring a thin, microporous polycarbonate film with precisely defined, cylindrical pores, these hydrophilic Polycarbonate Track Etch (PCTE) membrane discs deliver accurate surface capture at a 1.0um pore size across a 25mm diameter. The membrane is treated with polyvinylpyrrolidone (PVP) to provide consistent wetting of aqueous samples, and its smooth, translucent surface captures all particles larger than the pore size for precise size separation and clean microscopic analysis. Each disc measures 25mm in diameter and ships nonsterile in packs of 100.

Key Polycarbonate Track Etch Membrane Characteristics

• Hydrophilic, PVP-treated surface wets readily and processes aqueous samples without pretreatment.
• Precise cylindrical pores are produced through a two-step track-etch process that controls pore size and density for accurate size separation.
• Surface capture retains all particles larger than the pore size on the smooth, flat membrane face rather than within a depth matrix.
• Low protein binding minimizes sample loss and non-specific adsorption.
• Thin, translucent structure resists chemical staining and eases optical and microscopic visualization of retained particles.

Key Construction Characteristics

• Material: Polycarbonate Track Etch (PCTE) membrane.
• Format: 25mm diameter disc, white, plain (not gridded).
• Sterility: Nonsterile, supplied 100 per pack.

The narrow pore distribution and well-defined membrane structure provide predictable retention and reproducible results across samples. With low non-specific binding and a clean, flat capture surface, these discs maintain sample integrity and support accurate downstream analysis.
